| Title | The Study Intake Manifold Volume for Engine Performance | ||
| Keyword | |||
| Abstract | The purpose of this study was to enhance the intake manifold volume ratio and establish a set of experimental methods and processes. Experiments use current commercially mainstreams, which are Toyota Altis, Mitsubishi Virage and Nissan Sentra as three displacements of 1800 CC the car. They are installed different thickness of the hollow accessories to change the intake volume between the intake manifold and throttle body assembly in order to compare different volumetric efficiency of the intake manifold. We measure the actual performance data of the engine based on the horsepower chassis to analyze and verify. What happened to the torque and horsepower output engine performance curve case were found out when the intake manifold volume increases, and also to obtain the best output efficiency under different engine speeds. Experimental results show that when the intake manifold volume increases to 1.51% , its maximum torque increases to the rate of 5.83% , and its horsepower enhances to the rate of 5.94% according to the general urban driving speed range of frequently used 2100 to 2400 rpm. If the engine output characteristics meets the expectations of driving, the frequency of heavy throttle and fuel consumption will be reduced. This study confirmed that when the volume of the intake manifold is in a limited increasing, it helps the upgrade of the engine performance. |
